What you need to learn in this chapter
In this chapter, we will be learning about algebraic expressions.
We will learn how to use letters to represent unknown quantities and determine whether the value of the variable varies or is fixed. We will also learn how to derive algebraic expressions from arithmetic expressions that represent a situation. Additionally, we will explore algebraic expressions involving basic arithmetic operations.
We will make generalizations about repeated multiplication of algebraic expressions and practice multiplying and dividing algebraic expressions with one term.
Topics in this chapter
1. Variables and algebraic expressions
What you will learn in this topic
- Use letters to represent quantities with unknown values. Hence, state whether the value of the variable varies or fixed, with justification.
- Derive algebraic expressions based on arithmetic expressions that represent a situation.
- Determine the values of algebraic expressions given the values of variables and make connection with appropriate situations.
- Identify the terms in an algebraic expression. Hence, state the possible coefficients for the algebraic terms.
- Identify like and unlike terms.
- Add and subtract two or more algebraic expressions.
2. Algebraic expressions involving basic arithmetic operations
What you will learn in this topic
- Make generalisation about repeated multiplication of algebraic expressions.
- Multiply and divide algebraic expressions with one term.
